Been wanting to do this for a while will be doing a marking one soon (when i can be bothered to do the grey scales)

~Brown

HazelUsually found on horses with lighter coloured coats such as palomino and buckskin.BrownFound on most horses.The skin will be dark around it.Dark Brownusually found on the darker coats such as black and dark bay but also found else where.

Blue

Leaked Blueim not sure if its the proper name but meh.where the inside of the eye is darker than the outside of the eye.Blue on splashWhen the horse has the Splash gene it creates a blue eye no matter if it has a white marking around the eye or not.Bluewhen the horse has a light coat such as white or Cremello it makes the ye white and the skin pink.

Rare Cases

Greeni cant find an image on deviant so here [link]Foals are some times born with green eyes that change to blue in later life.Green eyes are extremely rare!!!Heterochromia:thumb113836493:Can happen randomly or when a white marking passes though half the eye it courses Heterochromia where the eye is both blue and brown.It may mean the horse is blind but most times its not.Blind:thumb289691653:if the horse is blind its eye might be completely black or white or a mixture of both.it can happen in both or just one eye.

Thank You for creating this, very nicely done.As another poster noted yes there are the yellow tiger eyes mainly in Paso Finos. There is also a new combination that is cause by a newly discovered dilution called Light Black (it shows more on black based but still appears on red based) that is in Arabians, Friesians, Morgans, Andalusian, Australian Quarter Ponies, and Dutch Draft. Since the Arabians in this case are pure bred it looks to be a dilution gene that has been around, but hidden for generations and it most likely is showing in these other breeds here and there from and Arabian ancestor.www.hippo-logistics.com/newdil…www.theequinest.com/colors/dil…

the eyes are blue on the foal and change to either a hazel/blue or brown/blue. The iris around the pupil stays bluish while the rest of the eye is hazel, light brown, or brown.Blue eyes will sometimes be found in Palominos though no one knows why only some do. It's not something obvious like a white pattern gene. I've seen a few hazel/green eyes in dilutes especially Champagnes which do sometimes stay into adulthood, especially if they are a combination of dilutes -cream/champagne/pearl.

Usually the random blue eyes on solid horses are because of hidden white markings in the genes, they are there, just not expressed for one reason or another. It seems to take a combination of genes to actually get some markings to express. Two solid colored horses that have hidden white markings such as splash, sabino, or overo have a chance of producing unexpectedly marked offspring. Even to the point where in AQH solid colored or minimally marked horses were producing crop out sabinos and overos until the rules changed. Good example are Leopards, there are even solid Leopard complex horses, ie no white markings, but they may have the speckling esp around the eyes and/or striped hooves. Even a totally solid offspring or a Leopard might have some of the modifying Lp genes so that when bred with a Leopard horse, the offspring have a chance of inheriting those, possibly spectacular modifiers.

To anyone breeding a breed known to have Frame Overo, always get your horses tested, there have been to many cases where the Frame Overo has been so minimal (white face marking or leg marking) or hiding in a 'solid' or splash or sabino horse and the offspring bred with another with Frame Overo has produced a lethal white.
